5.9 Dangerous Materials
・
PVC
PVC is a common material that cannot be laser
processed. When burned, PVC produces HCl
(hydrochloric acid gas) that will harm the lungs and
corrode machine parts. When PVC is burned, it
also produces highly carcinogens such as dioxin or
polychlorinated biphenyls. PVC is often presented in
the forms of sticker, film or transparent sheet.
・
ABS
ABS is a common material that cannot be laser
processed. ABS tends to burn “dirty”, producing A
(acrylonitrile), B (butadiene), and S (styrene), which are
carcinogens category 2B, 1 and 2B.
